Ok so I have a 99 honda civic ex 1.6 liter engine and the check engine light came on due to a slow response on the primary oxygen sensor. according to my local honda dealership this will cost $511.72...needless to say i really don't want to pay that much. If any of you know how to replace one of these can you help me please, or give me a site that explains how to (preferabily with pictures ) or even where it is located at. thanks

 

Just get a universal 4-wire oxygen sensor from an automotive store and splice it to the stock O2 sensor plug.

yeah those 02 sensors are pricey. You should pickup a Manual for the car.

 

wow thanks a lot...i have looked all over for a diagram and didn't find a single one. at least i know where to look now

that sucks man, my local honda dealer is sweet. theyll print any diagram for me, give me bolt sizes even when i tell them im going to get them somewhere cheaper. but hey you got what you need

 

go to the auto parts.
they can sell you univeral o2 and OEM plug o2 sensor.
the OEM plug one will cost you a bit more. but is less than $150.
do it yourself. dealer is a rip off

 

all you need
7/8 wrench

And a soldering iron to splice the wires if the plug doesn't fit.

 

OE identical front
OE identical rear
Universal rear

Piece of cake to do yourself. Put some anti-seize on the threads when reinstalling.
